乳胶型粘接剂及粘接片
摘要：
本发明提供了含有聚合物乳胶和交联剂的乳胶型粘接剂，所述聚合物乳胶为，能够交联剂不存在的条件下形成四氢呋喃萃取率高的干燥涂膜，并且其溶出成分为特定的重均分子量。进一步，由含有交联剂的所述乳胶型粘接剂形成的粘接剂层，在加热经时前后都呈现高的四氢呋喃萃取率。
摘要（英）：

The invention provides a emulsoid type adhesives containing polymer emulsion and crosslinking agent, which enables form dry coating with high extraction ratio of THF in condition of absentance crosslinking agent, and stripping component as predetermined weight average molecular weight. Further, adhesives layer formed by the emulsoid type adhesives containing crosslinking agent presents high extraction ratio of THF before and after heating.
